Samsung SCH-i830 / IP-830w

i have the i730 and i havent had problems with accidently accessing the internet...i have the pay as you go plan and i did not need to write any letter. I chose the pay as you go plan because I got this phone for all its other features and I hadn't planned on accessing the internet on a regular basis with it. However I gotta say if you plan on using the internet on your phone monthly id recommend a plan other the pay as you go...i accessed 2 web sites one time and it cost me almost $30 for that month.
